延迟抖动 meaning in English
delay jitter
Examples
- The jitter ( or delay jitter ) determines the maximum allowed variance in the arrival of data at the destination
抖动（匮称延迟抖动）指的是数据到达目的地所需时间的最大偏差。 - The simulation experiment results using ns software tool show that the scheme can flexibly control the length of queue and reduce the jitter of delay
通过ns仿真实验表明了该算法可以很好的控制队列长度，降低延迟抖动。 - The current internet only provides the service called best - effort , in which , all traffics are treated indistinguishably and compete for the network resources equally . this service model is insufficient for those applications that have special requirements for bandwidth , delay and delay jitter , and these requirements result in the emergence of concept of quality of service ( qos )
现有的internet网络基本上只提供“ best - effort ”的服务，在这种服务模型下，所有的数据流( traffic )被“一视同仁” ，公平地竞争网络资源，这对一些对带宽、延迟、延迟抖动等有特殊要求的应用来说，无疑是不能满足要求的。 - It is necessary to investigate the relationship between traffic and network performance parameters because network traffic plays an important role in network performance research and its characteristics exhibit by network performance parameters such as packet loss , delay and delay jitter 。 this is the work of traffic measurement , modeling and analysis
正是由于流量在网络性能研究中这种十分重要的地位,同时流量的特征属性通过外在的网络性能参数(丢包,延迟,延迟抖动)表现出来,那么就有必要探讨两者之间的联系,这即是属于网络流量测量与分析的工作。 - This paper first introduces the aspects of network performance research based on traffic measurement , modeling and analysis and its state - of - the - art , secondly summarizes then the concept , models and analysis tools of self - similar traffic , and analyzes scaling behavior of packet loss with self - similar traffic input by wavelets method , thirdly introduces hidden markov model and its applications on network performance research , and then explores the cross - traffic inferring technology and the disadvantages of existing methods . after that the paper develops a new method for cross - traffic inferring based on delay jitter measurement , proves its correctness by experiments , and applies it to self - similar traffic background and real traffic trace to investigate its availability ,
本文首先阐述了基于流量测量与分析的网络性能研究方向和研究现状,而后介绍了自相似流量的基本概念和相关建模和分析技术,并采用小波分析的方法分析了单路复用网络模型在自相似流量下丢包的尺度特性,其次介绍了隐马尔可夫模型以及其在网络性能研究中的应用,最后在此基础上考察了网络流量推断技术,分析了现有的方法的不足之处,提出了一种新的基于探测流延迟抖动测量的流量推断测量技术,通过实验证明了该方法的正确性,然后将其应用到自相似流量背景下考察了其对自相似性的推断刻画能力,并且通过实际流量检验了其有效性。
